Evaluation of the equilibrium assignment

  • Because the procedure only terminates when all routes of any OD pair are in the balanced state, the procedure provides more realistic results than the incremental procedure.
  • In the vast majority of networks, equilibrium assignment achieves the best computation times. The computation time of the equilibrium assignment depends largely on the volume/capacity ratio in the network. Because new routes can be found in every iteration step for a strongly saturated network, more computation time is required in this case.
  • Compared to stochastic assignment procedures (Stochastic assignment and Dynamic stochastic assignment), equilibrium assignment provides distinct network volumes. Compared to the number of calculated iterations, the gap is a more objective termination criterion.
  • Compared to other equilibrium methods (e.g., Bi-conjugate Frank-Wolfe or LUCE), more accurate solutions, i.e. small gaps, are possible with equilibrium assignment in many networks.
